Hi Tweaker,
You know my thoughts about the "Panorama's" in your previous posting regarding them compared to the GR Research "Diluceo" but I thought I would share a few more thought's.
I know what you mean about the dispersion limit of certain types of speaker's. I use to really like and thought there could be nothing that would ever come close to electrostatic panels for the highs but the sweet spot was so very very small. The sign on my wall said "Only one person at a time in the listening position"!

until the ACI "Sapphire's". That was the end of electrostats!
Once you set the Panorama's in place, that is where they will stay!
You will not have any problem with the height difference between you and you wife. The only tweak that I did was to plug the port's. I prefer the sound better when having a sub included.
WARNING! These ACI Panorama's are fast, dynamic, have superb bass extension, wonderful imaging and will make you stop what you are doing in other rooms of your home to listen to your system.
They sound great all over my home. I am very happy!

I recommend taking ACI up on their 30 day policy.
